During the construction,hot asphalt mixture,particularly modified asphalt mixture of asphalt sticking problem of construction seriously.Althought the Asphalt pavement Construction Specifications clearly stipulates that the haul car plate end rolling wheel need to smear the isolation agent or anti-seize compound in order to alleviate the problem of asphalt mixture with sticky when the transportation and compacting asphalt mixture was forming,it did not give a specific isolation agent usage and the control indexes.We investigated the construction site of each asphalt pavement while found that the use of a isolation agent in a relatively blind chaos.Curuently,the constructing of asphalt pavement and asphalt mixes transportation in domestic,plastic Core-rubber-tires and truck plates generally use diesel,vegetable oil,etc,as a isolation agent.Because the isolation agent for asphalt mix has a significant role to dissolve,it adversely affects the Pavement performance of asphalt pavement when the isolation agent resided on asphalt pavement.The dilution of oil asphalt isolation agent to the surface of road,which can cause the problem that the road surface asphalt film is easy to peel off and the road surface of the short time of the material is easy to expose.Both the two problems can accelerate the rate of the water damage of the adphalt pavement surface The method of watering to the steel wheel roller is commonly used to prevent mix asphalt materisl sticky wheel.However,when we water more,the temperature.of mixture surface is reduced faster,especially.When the construction is in low temperature.It severely impacts the compaction degree of mixture,and influences the road pavement performance.The developing thinking is putforward according to the performance requirements and evolution methods of isolation agent.The paper expounds the requirements and primary of raw materials,the preparation mechanism and the development process of isolation agent The paper expounds the requirements and primary of raw materials,the preparation mechanism and the development process of isolation agent emulsion,and the proportional selection and the processing craft of the main material.Finally,the preparation technics of isolation agent is confirmed,a new HZ environmental protection protection isolation agent is developed.It is validated from different effects,such as the isolation performance,the influence of asphalt indicators,the influence of the asphalt indicators,the influence of index of asphalt,the inderlaminar properties an environmental protection,The performance advantages of HZ asphalt isolator agent are analyzed by comparing with other isolation agent in rubber wheel roller,steel wheel roller,the construction tools the use of the transport vehicle body.The research and development of new environmental protection asphalt isolation,is not only to meet the construction convenience,replace the existing material,change the present situation of blind using isolation agent,but also can inprove the compaction degree of asphalt concrete pavement and road performance,optimize the working conditions and reduce the environment pollution,It has important significance in the development of highway construction and building the Environmentally Frindly traffic develop[ment model.
