Asphalt pavement in the traffic load and the impact of climate, with the passage of time, road conditions and service capacity will gradually deteriorate, in order to prevent the early destruction of pavement, extend the service life of the pavement, Kongtong segment using asphalt gravel synchronous sealing technology Preventive maintenance of highway pavement. The technology is synchronized in the same second sprinkling asphalt and spreading aggregate, so that between them with the largest…

According to the design width, paving technology and paving quality of the road, the maximum paving width, the maximum paving thickness, the paving speed, the paver productivity (t / h), the paving width Shop forming accuracy and paving quality. The main parameters and basic parameters of the asphalt concrete paver are fully considered to meet the requirements of the engineering design and the construction quality is ensured and the productivity (t / h) of the asphalt concrete mixing…
