Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In recent years, the application of asphalt concrete in China is more and more extensive, the asphalt concrete is mainly used for paving semi-rigid base asphalt pavements, and the proportion of asphalt concrete pavements in expressways built in China is as high as ninety percent. The asphalt concrete pavement needs to undergo construction processes such as mixing, transportation, paving, rolling, maintenance and the like, wherein the rolling process is related to the stability, compactness and strength of the asphalt pavement. Therefore, the rolling process is the most important process in the construction of the asphalt concrete pavement. The main construction process comprises initial pressure, vibration pressure and final pressure.
The initial pressing process mainly aims to stabilize the asphalt concrete, improve the bearing capacity of the asphalt concrete, achieve certain initial strength and ensure that the vibratory roller does not cause construction problems of upwrapping, pushing, sliding and the like on an asphalt concrete pavement in the re-pressing process. Usually, a static road roller is adopted for rolling for one to two times, attention needs to be paid to rolling along with a paver, the construction temperature needs to be kept above 120 ℃, and the rolling speed is preferably 2 to 3 km/h;
the vibration pressing process is also called re-pressing, is one of the most critical processes for ensuring the rolling construction quality of the asphalt concrete, has good vibration pressing, can ensure the compactness and the strength of the asphalt concrete, and improves the physical characteristics and the later use performance of the pavement. Usually, a double-wheel or single-wheel vibratory roller is adopted after initial pressing, continuous and uninterrupted construction needs to be carried out, and the roller cannot be stopped randomly in the midway. Most of asphalt concrete surface layers are compact framework structures, the thickness of the surface layers is small, in order to prevent the overpressure phenomenon, a high-frequency low-amplitude vibratory roller is not suitable to be adopted, a low-frequency high-amplitude vibratory roller is suitable to be adopted for rolling for four to six times, the vibration frequency is preferably 30Hz to 35Hz, the amplitude is preferably 0.3 to 0.8mm, the surface layer with the thickness smaller than 30mm is not suitable to be rolled by the vibratory roller, the construction temperature is required to be kept above 90 ℃, and the speed is preferably 4 to 5 km/h;
the final pressure is to eliminate wheel marks, ensure the flatness of the asphalt concrete pavement, improve the driving comfort level and prevent the later-stage damage of the structure, so that the process is not suitable for rolling by adopting a vibratory roller so as to avoid influencing the flatness of the asphalt pavement and influencing the use effect. Therefore, a static pressure road machine with low tonnage is adopted for rolling for two to three times, the speed is preferably 2 to 3km/h, the construction temperature is controlled to be more than 90 degrees, the compaction degree of the asphalt concrete is higher at the later stage of vibration compaction, if the vibration rolling is continued, when the compaction degree reaches a certain peak value, because the granularity of the asphalt concrete is enhanced, namely the strength and the rigidity modulus are increased, the jumping vibration stage is started, and the stage mainly shows that: the vibrating wheel can leave the compacted road surface at a certain moment, and the construction effect and the efficiency are influenced. The bounce stage is related to the selection of parameters such as the frequency and the amplitude of the road roller to a certain extent, so that the working technical index of the vibratory road roller needs to be reasonably selected;
therefore, the vibration frequency explorer is arranged at the bottom of the road roller, can receive the vibration frequency of the road roller and transmit the vibration frequency to the cab, and is convenient for road rolling with better effect.
