What should be paid attention to in the compaction of asphalt pavement?

图片
 After the asphalt mixture is paved, it enters the compaction process. The compaction of asphalt mixture is an important aspect of asphalt pavement construction, and it is a very important process. In the process of pavement compaction, it must be equipped with sufficient large-tonnage compaction equipment, and try to use the most advanced two-wheel vibration roller. The compaction of asphalt pavement generally includes the following aspects: The initial pressure of the road surface, the re-pressure of the road surface and the final pressure of the road surface. 1. Initial pressure of the road surface The initial pressure is the primary link of road surface compaction. This link is generally carried out directly after the mixture is paved. Slow rolling 2-3 times, the temperature of the initial pressing link is generally kept between 110-140 degrees Celsius. Therefore, as long as the compaction equipment with relatively small tonnage can play a very good effect. Under normal circumstanc

When Did Asphalt Pavement Exist?

图片
 1. Development history of asphalt pavement: About 600 AD, the first asphalt road was built in Babylon, but the technology was lost soon after. In 1712, taking the discovery of rock asphalt in Switzerland as an opportunity, it was subsequently discovered in Germany, France and other countries. Around 1850, France first used rock asphalt for road pavement. In 1854, a thin-layer asphalt pavement close to the present was built in Paris, which can be called the beginning of hot paved rock asphalt pavement. The rock asphalt used at that time was limestone infiltrated with 6-10% asphalt, which was broken into fine particles, heated, paved and rolled, and the asphalt pavement was formed. The maximum particle size is 2.5mm, and the powder particle size of 0.074mm can reach more than 40%, which became the advanced pavement structure at that time. The United States did not import a large amount of rock asphalt from France and Switzerland until after 1850, and began to build rock asphalt pavement

How to choose a double drum roller?

图片
When choosing the double drum roller, we should consider the facts from two sides: soft power and hard power. For the hard power of double drum roller 1. The ability of stability and continuous work 2. The self-weight of the double drum roller and the exciting force generated by the vibration system should meet the requirements. 3. Various vibration modes are available 4. Flexible operation 5. Water spray capacity 6. Anti-collision capability 7. Intelligent Detection 8. Staggered Wheels For the soft power 1. Reasonable price and high cost performance 2. After-sale service 3. Repair and replacement are simple and easy. 4. Big Brands 5. High residual value of equipment See details:  https://fbroadroller.com/the-twin-drum-roller-in-my-heart/     Twin Drum Roller For Sale >>>

The Use Of Double Drum Vibratory Roller

图片
  1. During operation, the road roller should start first before it can start to vibrate, and the internal combustion engine should be at medium speed first, and then adjust to high speed. 2. Stop the engine first when shifting and reversing, and reduce the speed of the internal combustion engine when shifting. 3. It is strictly forbidden for the roller to vibrate on solid ground. 4. When rolling the soft roadbed, it should be rolled 1-2 times without vibration, and then vibrated and rolled. 5. When rolling, the vibration frequency should be consistent. For the adjustable double-drum vibratory roller, the vibration frequency should be adjusted before the operation, and the vibration frequency should not be adjusted without vibration. 6. The adjustment of the clutch, shock clutch, and brake of the reversing double-drum vibratory roller should be carried out after the main clutch is disengaged. 7. When going up and downhill, fast gears are not allowed. During sharp turns, including artic

Classification Of Small Road Roller

图片
 As a representative model of construction machinery and equipment, small road roller is always busy on construction sites such as highways, bridges, and buildings. Because of its low price, small size, convenient maintenance, unique advantages, flexibility, multi-function, and high efficiency, it is very popular with users. From the working mode, the small road roller can be divided into two types: static pressure roller and vibratory roller. Static rollers can be divided into two types: tire rollers and drum rollers. The tire rollers include self-propelled tire rollers and towed rollers. Drum rollers include two-wheel and two-shaft rollers, and three-wheel and two-shaft rollers. There are five types of vibratory rollers: walk-behind vibratory rollers, ride-on vibratory rollers, tire-driven vibratory rollers (bumps, smooth wheels), two-wheel tandem vibratory rollers (articulated integral type), and trailing vibratory rollers.

Technical Quality Status Of Compactor Machine

图片
  In highway construction, a compactor machine is a very important piece of equipment. No matter the subgrade, the ground base, base layer, and surface layer need to be well compacted to achieve a certain degree of compaction, improve the bearing capacity of the road, and prevent subsidence, moisture penetration, etc. With the rapid increase in traffic volume and the further development of highway construction, the construction department has put forward higher and higher requirements for compactor machines. When a compactor machine is used for compaction, common problems are less than desired compactness and uneven surfaces. The compactness does not reach the expected value. First, the selected road roller is incompatible with the construction process used, and ultimately the expected compaction effect and productivity cannot be achieved. For example, the compaction of the foundation is too low, the selection of vibration parameters, the determination of the thickness of the auxiliary
