At present, a total of 119.15 kilometers of asphalt paved roads have been paved in trunk roads maintained in our province; an area of 630,000 square meters. There have been six sections of the road maintenance section, two directly under the unit and other units of personnel trained by the asphalt pavement construction and maintenance of the field; the construction unit also has some of the construction operation of the mechanical tools; also established a number of construction operation system. Asphalt pavement treatment technology, but also from the general surface treatment, and gradually developed to the characteristics of our province paving asphalt pavement wear zone. The cost of this wear layer has been reduced from 4,700 yuan per kilometer of the 5.5-meter-wide road surface to 4,100 yuan. On the construction method
