Asphalt Pavement Recycling with Reclaimed Asphalt Pavement
As part of the FHWA recycled materials policy, the FHWA actively promotes asphalt pavement recycling and technology. There are three key requirements that must be satisfied for asphalt pavement recycling to be successful. Recycled asphalt pavements must: be cost effective, be environmentally responsible, and; perform well.This study is devoted to finding a solution to an important problem of increasing the accuracy of assessing the fatigue stability of composites based on recycled asphalt concrete. Another problem for solving was a selecting optimal and effective ways to improve their physical–mechanical properties during modification by polymers.

A review of design methods for cold in-place recycling asphalt
The use of cold in-place recycling (CIR) asphalt mixtures is a time-saving and environmentally-friendly technique for repairing aging and damaged asphalt pavements.The technique requires that a section of the layers that form the asphalt pavement is pulverized, mixed with a recycling agent, and repaved in place.This Millions of tons of reclaimed asphalt pavement (RAP) and reclaimed aggregate or reclaimed inorganic binder stabilized aggregate (RAI) is produced every year in China. The cold recycled mixture (CRM) technology reduces fuel consumption, emissions, and cost and utilizes the high content of RAP. In this paper, six types of CRM with Coatings Free Full-Text Study on Cold Recycled Asphalt

Review on the Effect of Curing on Cold Recycled Asphalt Mixture
The cold recycling procedure includes excavation of existing asphalt pavement to the required depth usually between 15 and 38 cm, milling the excavated materials, sizing and screening/gradation control, addition of recycling agent/additive, mixing, placement and compaction of the recycled mixture and surface course Then the gradation of recycled asphalt pavement aggregate is of the required values to reuse in the mixture, while the flow ratio, the splitting strength ratio, Simone A.

Cold Recycled Asphalt Mixture using 100% RAP with Emulsified Asphalt
The rehabilitation process of asphalt pavements using the technique of milling and filling can cause several environmental problems due to either the disposal of the milled asphalt mix or the exploration of natural resources. One alternative to mitigate these impacts is to reuse this milled material, known as reclaimed asphalt pavement (RAP), in The curing of cold recycled pavement can also increase the fatigue life of mix due to decreased air void content and Li Xiangguo YIN, Xiaobo MAB, Huang Jian LI, Junxiao, (2013) Cement-fly ash stabilization of cold in-place recycled (CIR) asphalt pavement mixtures for road bases or subbases.

Cold In-Place Recycling Pavement Interactive
Cold In-Place Recycling. Cold in-place recycling (CIR) is the processing and treatment with bituminous and/or chemical additives of existing HMA pavements without heating to produce a restored pavement layer (AASHTO, 1998 [1] ). It involves the same process of cold plant mix recycling except that it is done in-place by a train of equipment.Emulsified Asphalt Cold Recycled Technology for Highway Pavement: a State-of-the-art Review. 摘要 公路路面乳化沥青冷再生混合料作为一种绿色铺面材料,因在延长道路寿命的同时增加了沥青旧料的利用率,逐渐受到关注。. 近年来,学者们针对如何提升乳化沥青冷再生混合料使用品质公路路面乳化沥青冷再生技术综述

Fatigue damage calculation of cold recycled asphalt pavement
Through the above method, simulation calculations were performed for cold recycled asphalt pavement structures with different cement-stabilized aggregate (CSA) base stiffnesses. The results show that the fatigue damage accumulation of the EACR layers reaches its highest value in winter and midday hours, owing to the Cement-fly ash stabilization of cold in-place recycled (CIR) asphalt pavement mixtures for road bases or subbases.
