Use of recycled concrete aggregate for pavement construction

The use of recycled concrete aggregate (RCA) for the production of concrete is limited to low strength concrete due to the difficulty in quality control and poor strength. RCA is, therefore, primarily used in pavement base and subbase courses as a Utilisation of RCA in concrete slabs offered a better savings in cost than using them as roadbase materials. Shi et al. [4] attempted to assess the potential Utilisation of recycled concrete aggregates for sustainable

Recycled Clay Masonry and Recycled Concrete Aggregate Blends in Pavement

This paper presents the engineering characteristics of blends of recycled crushed clay masonry (RCM) with recycled concrete aggregate (RCA). The proportion by dry mass of RCM was 10%, 20% and 30% of the total mass.Portland cement concrete (PCC) has been widely used in construction of bridges, roads, runways, buildings, etc. It is mainly composed of aggregates, cement and water. Stones are crushed to produce the aggregate.

Sustainability Assessment of Using Recycled Aggregates in Concrete

The mechanistic design of a concrete block pavement (CBP) can be very complicated and often requires the use of computer programs. This paper presents a new mechanistic-empirical method, which is implemented in a computer program (DesignPave) that calculates base course/sub-base thicknesses for a range of design inputs such as This study investigates the feasibility of using recycled concrete aggregate (RCA) as a partial substitution of natural aggregate in pavement engineering. Despite RCA’s good properties, such as polishing value and freeze-thaw resistance, its use is limited by low resistance to fragmentation and high-water absorption.

Recycled Asphalt Pavement Materials in Transport

Transportation infrastructure is one of the largest consumers of natural materials. To improve the environmental quality and sustainable development of transportation infrastructure, it is important to The reason is that, although the source of waste concrete is quite cheap, various treatment processes to produce RCA require additional costs comparing to landfill disposal. Besides, the recycled concrete pavement may cause more negative effects in the use and maintenance stage of pavement life (Shi et al., 2019). However, it avoids the Natural gravel-recycled aggregate concrete applied in rural

Fatigue of Cold Recycled Cement-Treated Pavement Layers:

Fatigue is the main design criterion for cold recycled cement-treated mixtures (CRCTMs). However, the literature shows that the fatigue behavior of such mixtures is still not well known.
