Page 1 of 8 Specifications for Cold Constructed Asphalt Material Placed on Various County and Township Roads Bids will be received by the Champaign County Commissioners for the project titled "2020 Cold Constructed Material Placed" via Bid Express until 9:00 A.M., April 21, 2020 for the installation of a cold mix overlay on …
The list below covers the different types of pavement distresses that are often found on asphalt pavements. Defects in Asphalt Pavement. Fatigue/Crocodile …
Cold Constructed Asphalt Pavement (CCAP) is a unique asphalt product consisting of open-graded aggregates combined with a gelled multi-grade asphalt binder. Gelled asphalt binder produces thick asphalt films on the aggregate creating an improved form of cold mix asphalt with no risk of emulsion draindown often associated with conventional open ...
A layer of asphalt mix placed between the base and the surface courses in the pavement structure. Flexible Pavement They have a ride surface constructed with a combination of asphalt cement and aggregates. Batch Amount of concrete produced in one mixing operation. Cross Slope The transverse inclination of a road way or other surface. …
This will, in theory, increase the cold side HMA temperature and make the constituent asphalt binder less viscous and stickier. Typically, an infrared heater is mounted on the paver and aimed at the cold joint side. It is …
A chip seal gets its name from the "chips" or small crushed rock placed on the surface. Asphalt emulsions used in chip seal applications contain globules of paving asphalt, water, an "emulsifying agent" or surfactant, polymer, and sometimes a "rejuvenator.". Soap is a common form of a surfactant. In washing clothes or dishes, the ...
Cold constructed asphalt pavement is an asphalt binder mixed with the aggregate that is mixed in a pug mill or at a plant at warm temperatures for use with low to medium volume roads. The benefits include road …
Asphalt pavement consists of multiple layers of asphalt with a progressive decrease of nominal maximum aggregate size from the bottom to the top, which can be constructed by the double-decked or the conventional paving method (i.e., layer by layer). Reliable interface strength between the fine- and the coarse-grained layer of asphalt mixture is …
Porous asphalt pavement is a sustainable infrastructure tool used to benefit urban resilience. This paper summarizes the design, construction, and maintenance practices of porous asphalt pavements (PAPs) specific to cold regions. It includes discussions on the structural design considering frost depth and frost heave of subgrade …
For Cold Constructed Asphalt Pavement (CCAP), cold mix asphalt is created through a combination of aggregate mixed at ambient temperature with …
This product works on parking lots, chip seal applications, and all other types of road surfaces. We can use different mix formulations and stone materials based on the surface we are trying to achieve. CCAP - Cold Constructed Asphalt Paving AE 200 is paving mix with a 30% savings over traditional hot-mix.
Cold Constructed Asphalt Pavements Our CCAP line is the hidden gem of the asphalt paving world. They are durable enough to be placed on low and medium-volume rural roads, flexible enough to knead back together after being distorted by frost heaves, and economical for everyone.
As described above, the ESAL is the standard unit of pavement damage and represents the damage caused by a single 18,000 pound axle load. Therefore, a two-axle vehicle with both axles loaded at 18,000 pounds would produce two ESALs.
A chip seal gets its name from the "chips" or small crushed rock placed on the surface. Asphalt emulsions used in chip seal applications contain globules of paving asphalt, water, an "emulsifying agent" or surfactant, …
CCAP or Cold Constructed Asphalt Pavement is a blend of gelled asphalt and additives that is mixed with pre-approved aggregate through a …
Pavement planing shall consist of cold planing a continuous width of asphalt concrete pavement, to the limits shown or specified in the Contract. The depth of planing below …

Cold-mix asphalt is a mixture of asphalt and a solvent and/or water, aggregates, reclaimed asphalt pavement (RAP) and other minerals typically used for patching and for repair of small sections of pavement. The asphalt and solvent portion, excluding the other components of the cold mixture, is often referred to as "cutback …
CCAP mixtures have been used by numerous agencies across Indiana and the Midwest. CCAP mixtures consist of hard, angular, open-graded aggregates that provide strength to pavement structures. The gelled multi-grade asphalt provides a thick, durable asphalt film that slows the progression of aging and thereby promotes increased pavement life. This …
Materials selection for porous asphalt pavement in cold regions Subgrade soils The types of subgrade soil greatly affect the performance of PAPs in cold regions, although PAPs have been successfully implemented in most soil types, including clays with low permeability and high frost-susceptibility.
PAC surfaces, which include open-graded friction courses, permeable friction courses, and drainage asphalt pavements, have increasingly gained acceptance among agencies and industry in the world. PAC might be susceptible to freeze-thaw damage in cold climates and require winter maintenance practices.
