The use of recycled concrete aggregates (RCA) instead natural in hot-mix asphalt mixtures is one the ways to achieve energy savings and reduce carbon emissions road engineering. However, cement mortar on surface RCA adversely affects adhesion properties between aggregates, leading a reduction performance characteristics mixtures. In this study, silane coupling agent (SCA) was employed improve R...

The volumetric properties of asphalt mixtures are important parameters for evaluating the performance asphalt. Volumetric (grading requirements, air void content, minimum and maximum voids filled with bitumen in mineral aggregate) usually presented first specifications. visualisation is therefore understanding composition an mix. A triangular representation requirements a valuable method to ill...

Waste fibers produced from manufacturing processes are a byproduct commonly deposited in storing yards and/or landfills and thus results in many serious environmental problems in Iran. If these waste materials could be advantageously put to practical use in any application, it would reduce the burden on the environment and landfills. This paper compares the performance of the stone matrix aspha...

The Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction , operation, management and economic efficiency of the Indiana transportation infrastructure. NOTICE The contents of this report reflect the views of ...

Stone Mastic Asphalt (SMA) has been broadly used on heavily trafficked roads and motorways in the UK due to its known stability durability. In this study, several sets of SMA mixtures were prod...
