1. Asphalt pavement daily cleaning effect and purpose Asphalt pavement in the road pavement project is a high-grade pavement, its main role is to carry the vehicle traffic, and road users not only the community of vehicles, as well as driving Personnel, pedestrians, etc., with the passage of time,[url=http://chipspreadermarket.com/road/505.html]waterproof bituminous emulsion uses[/url] the road debris, garbage gradually increased, affecting traffic safety. Asphalt pavement on the surface of the debris is: asphalt pavement surface of the asphalt film in the vehicle under the load, the gradual wear and tear of the gravel in the heavy vehicles, overweight vehicles under repeated effects, exacerbated the asphalt pavement wear and damage, so that asphalt Road surface density decreased, seepage coefficient increases, serious water seepage, the surface gradually formed pits. Spilled gravel will reduce the anti-skid performance of asphalt pavement, driving too fast or emergency braking, will lead to a car accident, to the driving and maintenance of production security risks. The road road that affects the road. 2. The effect of manual cleaning of the pavement in the daily maintenance work and the cost of input analysis, according to the current management of the highway management section mileage, the average maintenance of 3.8km per person, due to curing sections of asphalt pavement serious pollution, forcing the conservation workers will be the main energy To the road cleaning, other daily maintenance projects are not in place,[url=http://chipspreadermarket.com/road/2590.html]brown and sharpe milling machine for sale[/url] resulting in conservation within the scope of the overall conservation effect is not obvious. The traditional asphalt pavement cleaning is done manually according to every worker every week at least 2 to 3 times to calculate, put two brooms, every month to be put into labor per kilometer, the material cost of 250 yuan. Another clean and then repeated pollution, leading to repeated workers to clean, so that the workload increases, workers on the asphalt pavement burnout, negative emotions 3. Reference to the idea of ​​pavement hair dryer, asphalt pavement disposal of the continuity of pollution and the effect of manual cleaning, repeated analysis of the asphalt pavement to take the cleaning and maintenance measures, in the construction of asphalt pavement cleaning cement stable base after the top of the inspired, Consider whether you can use the air compressor or forest fire with the hair dryer to test. Through the Internet and field trials,[url=http://chipspreadermarket.com/road/5444.html]how to melt ice on driveway[/url] forest fire with the hair dryer engine power is small, the wind and the face is small, the effect is not very good. Air compressor effect is good, but the weight is large, bulky, easy to use to carry. To this end, decided to purchase a high-power road dryer to test.
