Reclaimed asphalt pavement (RAP) is the term given to removed and/or processed materials containing asphalt and aggregates. These materials are generated when asphalt pavements are removed for construction, resurfacing, or to obtain access to buried utilities.

Reclaimed asphalt pavement management: best practices by. Randy C. West Director. This document provides guidance for management of reclaimed asphalt pavement (RAP) materials from the time of collection through processing, mix design, and quality control practices

The key to utilizing asphalt pavement with higher RAP percentages is the ever-evolving technologies produced by raw material suppliers and equipment manufacturers. For example, during paving trials, a U.S. customer developed an asphalt mix consisting of 15 percent RAP, 3 percent recycled asphalt shingles (RAS) and 1 percent B2Last

The purpose of this research was to investigate the effects of reclaimed asphalt pavement (RAP) content and cement content on the strength and Both the RAP and base materials were sampled from the I-84 pavement reconstruction project performed in Weber Canyon near Morgan, Utah

In this project, unpolished reclaimed asphalt pavement (RAP) aggregate is tested in the form of RAP concrete to use it in rigid pavement application. Accordingly, mix proportions were designed by varying the percentage of RAP aggregate in RAP concrete. For rigid pavement application, concrete must satisfy required flexural resistance along with

Reclaimed Asphalt Pavement, RAP, Specifications, Balanced Mixture Design, Rutting, Cracking. 18. Distribution Statement. 6. 3.0 Reclaimed Asphalt Pavements. In order to evaluate the AASHTO M 323 recommended methods for specifying RAP in a mixture, the properties of the sampled RAP

A recent survey by the National Asphalt Pavement Association (NAPA) showed that state governments and agencies are increasing the adoption of sustainable technologies such as reclaimed asphalt pavement (RAP) nationwide. The survey stated that 66.7 million tons of RAP were collected

Reclaimed Asphalt Pavement (RAP) is produced when an old road is ground up by a milling machine. These millings or RAP is then saved, brought back to an asphalt plant and recycled into future asphalt mixtures. The majority of the asphalt mixtures around the country use RAP, averaging just over 20% by weight of the aggregate.

Reclaimed asphalt pavement (RAP) provides many advantages. The performance of a provincial road with an asphalt surface course containing RAP in Zhejiang, China was evaluated. The surface course was prepared by central plant hot mix recycling and asphalt concrete.

In Cuba, tons of construction and demolition waste (CDW) are generated during urban construction and reconstruction activities every year. The use of CDW, such as recycled concrete aggregates (RCA) and reclaimed asphalt pavement (RAP), in pavement construction is a viable solution to preserve the consumption of natural aggregates (NA), and to minimize the impact of landfill.

Reclaimed asphalt pavement (RAP), saves significant landfill space each year and decreases the amount of energy needed to manufacture asphalt, making it one of the most sustainable options for paving new infrastructure. According to the Federal Highway Administration (FHWA)

S.-C. Huang, H. Di Benedetto, in Advances in Asphalt Materials, The use of reclaimed asphalt pavement (RAP) has become relatively common practice in most countries, as it is both an environmentally and economically attractive proposition. A survey conducted by the Federal Highway Administration’s RAP expert task group shows that the average RAP content in hot mix is only 10–20%

RECLAIMED ASPHALT PAVEMENT AND RECLAIMED ASPHALT SHINGLES 1031.01 Description. Reclaimed asphalt pavement and reclaimed asphalt shingles shall be according to the following. (a) Reclaimed Asphalt Pavement (RAP). RAP is the material resulting from cold milling or crushing an existing hot-mix asphalt (HMA) pavement. RAP will be considered

Reclaimed Asphalt Pavement (RAP) is aged pavement materials reclaimed to be utilized over. In road construction industry, the utilization of recycled asphalt pavement (RAP) in hot bituminous mixtures can relief the manic use of natural resources and as a matter of course can cause less

The use of recycled materials is a key element in generating sustainable pavement designs to save natural resources, reduce energy, greenhouse gas emissions, and costs. The objective of this study was to propose a methodology for assessing the environmental and economic life-cycle benefits when using recycled asphalt pavement (RAP) materials in
