| The Asphah Managcr system is an automatic detection system equipped on a smart roller. , The system can make the compaction energy output always in WangZao state. And the change of the physical reference value (that is, the value of the road surface load capacity detected dynamically) during the compaction process is displayed in units of MN / m, and the detected data can be continuously converted into a deformation modulus value. And through the instrument display to the driver. The system can also print out the value, in order to facilitate the specific analysis, so as to improve the level of construction.Therefore, the compaction degree of the softening point can be reduced to a certain extent.
Intelligent roller in the console display on the Pleiades indicator information asphalt surface temperature, working speed, MN / m for the unit to show the dynamic deformation modulus value of several items. , & Lt;
Site compaction machinery and general construction procedures
Rolling process is divided into initial pressure, re-pressure, final pressure in three stages. , The initial pressure roller with CP30 tire roller 1 times, speed control in 2 Km. Compression using BMW vibratory roller vibration 4 times, speed control at 3.5 Km, and the final pressure with Hummer ?? I) 130 roller vibration music 1 times, static pressure l times. Speed ??control at 5 Km.
Comparing Methods and Implementation of Rolling Test of Two Types of
Paving rolling. The 60 111 is a test unit, which is divided into two test units, and the tire pressure roller is used for the first time. The two sets of two-wheeled roller (intelligent type and ordinary type) are separately tested for one test cell separately Rolling. In the first four times the process of re-testing constantly. , In each unit to take two rows of measuring points (longitudinal spacing of 5 m) for nuclear density test, each measurement point to take four values ??for the average calculation, while marking on the road, each compaction 1 times Are measured on-site real-time measurements. , The data recorded by the density and deformation modulus corresponding to the method. At the same time with the infrared thermometer to measure the surface temperature of the measuring point. , After the completion of the construction point of the drill core test, through the density comparison. And find out the comparison data of the control value for observing the deformation modulus in real time.
