we own dozens of advanced production lines and advanced production technology and high quality professional management talents to ensure excellent product quality.
Our asphalt mixing plant include:
our warm mix technology provides an environmentally friendly asphalt pavement. using our warm mix asphalt has benefits including lower energy consumption, lower fumes, lower odors, decreased emissions and easier placement. we also achieve better compaction on the road, extend our paving season and increase hauling distances.
conditions for fuels of asphalt mixture mixing plants are also different. Atent pres in China, the main fuel of asphalt mixture mixing plant is heavy oil. Recently, some mixing plants also use natural gas as the fuel. The range of using natural gas, however, is relatively small.
Demolition of existing asphalt pavement. To reconstruct the pavement it is necessary to demolish the existing pavement and take debris materials off the job site. Energy consumption associated with this process is shown in Table 5. (g) Construction of recycled base.
Warm mix asphalt (WMA) is created by mixing a solid chemical compound additive with hot mix asphalt in the plant. Except when a liquid additive is used to make WMA. But ask a contractor in ...

asphalt plants in the United States. Of these 3,600 plants, approximately 2,300 are batch plants, 1,000 are parallel flow drum mix plants, and 300 are counterflow drum mix plants. The total 1996 HMA production from batch and drum mix plants is estimated at …
Warm-mix asphalt technologies allow asphalt pavements to be produced at lower temperatures, which means reduced energy demands, as well as lower emissions during production and paving. As seen in previous FHWA/NAPA surveys covering the 2009–2016 construction seasons , the use of these sustainable practices has generally continued to increase.
of Pavement Preservation Processes for Asphalt Concrete Pavements Jim Chehovits Crafco, Inc., Chandler, Arizona, United States Larry Galehouse National Center for Pavement Preservation, Okemos, Michigan, United States ABSTRACT Use of pavement preservation treatments extends the remaining service life of asphalt concrete pavements.
Energy reduction in asphalt coating plants is not a well researched topic and has few published papers. This may be due in part to the previously lower cost of energy; however with rising energy prices and focus on associated carbon emission this topic is now receiving the attention of the asphalt industry.
As for warm asphalt, Harvey thinks its greatest importance might not be in energy savings at the asphalt plant, but in helping keep roads smoother for a longer time, as data seem to indicate that ...
The findings showed that three-quarters of Colas’ direct energy consumption can be broken down evenly between asphalt plant burners and fuel consumption by machines and vehicles. Colas systematically measures fuel consumption at its asphalt plant burners and methodically monitors over 500 plants.
Warm mix asphalt qualifies for LEED Credits thanks to the technology’s ability to lower emissions and reduce energy usage. Warm mix asphalt production and application conserve fuel by requiring significantly less energy making it a product geared towards sustainability and green-living.
which energy consumption can reach 60% of the total energy input into the construction and maintenance of a road over a 30-year service life (4, 5). In addition, a quantitative approach towards determining the energy benefits of warm and half-warm mix
tion of the mix at high temperatures is a source of concern as it requires high energy use, results in binder aging in the hot-mix plant and the generation of greenhouse gases. To address these concerns, the asphalt industry has
Asphalt mix producers continue to make significant use of energy-saving warm-mix asphalt technologies, with more than 99 percent of reclaimed asphalt pavement recycled.. In …
Low Energy Asphalt Pavement (or LEAP) is a durable HMA that’s made with 100% recycled materials.
Low Emission Asphalt (LEA) The road construction industry has been seeking, for many years, ways to reduce the amount of energy required to manufacture hot mix asphalt (HMA) in order to combine energy savings and environmental benefits.
As shown in Fig. 5, Zhu et al. (2014). stated that the energy consumption in mixing of SBS modified asphalt was lower than that of rubberized asphalt mixture. However, the total energy consumption of TBAR mixture was 13.66% lower than that of SBS modified asphalt mixture, followed by TOR and FBAR modified aspahlt mixtures, 13.61% and 5.75% ...
Welcome to PRIMACH, one of the leading manufacturers of Asphalt Mixing Plants (AMP), specialized heavy machinery and equipment for Hot Mix Asphalt (HMA), Warm Mix Asphalt (WMA), Stone Mastic Asphalt (SMA), Reclaimed Asphalt Pavement (RAP), modified asphalt, bitumen, as well as emulsion, meeting high standards and requirements for construction ...
The result is an intermediate grade mix that works just like conventional hot asphalt mix, but at a much lower temperature: about 230° F (110° C), a reduction of about 70°F (40°C).

Analysis of energy consumption in the production of hot mix asphalt (batch mix plant) Ivica Androjić, a Zlata Dolaček Alduk b a Faculty of Civil Engineering, …
Emulsified asphalt or cutback asphalt blended with aggregate warm at a hot mix plant, at a remote site in a portable pugmill, or in-place on the pavement. The emulsion mix is an economical alternative to hot mix asphalt, especially in remote locations.
–Water added to asphalt at plant to create asphalt emulsion •Water required to be potable and free of debris –Lower energy costs since less heating required to coat aggregate –Allows for lower temperatures of mixing and ... Warm Mix Asphalt (WMA) and Recycled Asphalt Pavement (RAP)
For an urban two-lane road in 2013, warm-mix asphalt paving costs were estimated at $852,238 per two-lane mile compared to $878,513 per two-lane mile for a hot …
Use greater quantities of reclaimed asphalt pavement (RAP) if same or better performance can be realized. Reduces cost of asphalt concrete if RAP available. Dependent on performance, energy costs of mixing, transportation.
Mixing: A more homogeneous mix is produced in a drum mix plant since the RAP is heated and mixed with the virgin aggregate and asphalt binder for a longer period of …
Warm mix asphalt is a kind of new pavement material, of which the mixing temperature (100°C to 140°C) is between hot mix asphalt and cold mix asphalt, and the performance is close to HMA.
