ii ABSTRACT OF THE DISSERTATION A Rational Approach to the Prediction of Reflective Cracking in Bituminous Overlays for Concrete Pavements By Thomas A. Bennert Dissertation Director: Ali Maher, Ph.D. Hot mix asphalt
asphalt binders on plant hot-mix operations and in-service aging. Kumar and Goetz (82) stated that the most important factor associated with binder hardening is the oxidation of the asphalt throughout the entire pavement thickness. Hardening at the surface is generally greater due to ultraviolet radiation and higher temperatures experienced.
Thin Overlays A new generation of thin-lift asphalt overlays called Thinlays are a popular approach to pavement preservation because of their ability to provide improved ride quality, reduce pavement distresses, maintain surface ...

Bituminous and modified bituminous flexible membrane systems are composite sheet membranes which are thermoplastic in nature but display variable elastomeric properties when modified. These sheets generally consist of bitumen (oxidized or modified), reinforcement, and surfacing materials.
Bituminous concrete used in the wearing course of the flexible pavement is mainly composed from bitumen which is a binder and aggregates and it is the most common material used in pavement because it provides better service in …
The chart below shows the progression of QC/QA in the production of hot mix asphalt. IDOT started with six projects in 1991. By August of 1994, a total of 255 jobs had been completed, which used approximately 6,000,000 tons of hot mix. Currently, all of the Districts in the state are at a 100% QC/QA implementation for hot mix production.

inch thick or thinner. Overlays thicker than 0.5 inch and thinner than 2 inches are referred to as thin overlay mixes (TOM). This section presents a synthesis from a review of existing literature on the current state of practice and research efforts on the use of think asphalt overlays for pavement maintenance, rehabilitation, and preservation.
So the use of recycled aggregates in concrete relieves the burden on the environment only when the aggregates are obtained from a near by site « 1 00 km) and if there is a scarcity of aggregates in the form of gravel or sand in the reg ion of the batching plant, which it could also be due to l i m its placed on the quarrying of such materials.

mix laid on sections 1, 2, 7, 8 and 10 on site 2 did not conform to the design mix. This resulted from the use of a high fines content sand, which had not been passed through the mixing plant drier, for determining the laboratory design mix.
The function of the hot mix plant is to heat the aggregates, add the asphalt cement and produce a homogenous asphalt mixture. The aggregate used to make the mix can be a single aggregate, but it is generally different sizes blended together through the cold feed bins to produce proper gradation.

Farmer County (Texas) Study A joint study by the Texas Department of Transportation and Texas Air Control Board included monitoring of stack emissions during mixing of HMA and ARHM at a drum-mix plant in Farmer County, Texas.(37) The drum-mix plant was a Barber-Greene plant equipped with a Venturi scrubber.
The mix is composed usually of aggregate and asphalt cements. Some types of bituminous mixes are also used in base coarse. The design of asphalt paving mix, as with the design of other engineering materials is largely a matter of selecting and proportioning constituent materials to obtain the desired properties in the finished pavement structure.
