I. Visual Appearance Acceptance Specifications The surface must exhibit a continuous and uniform coverage, with no air bubbles exceeding 3mm in diameter or any uncovered areas. Joints should have smooth transitions, forming a complete interface with the existing pavement, with color difference controlled within ΔE≤5. The fine-grained texture unique to micro-surfacing should be clearly visible, and aggregate distribution uniformity must reach over 90%.

The CTT Expo, Russia's largest professional exhibition for construction and engineering machinery, is the largest such event in Eastern Europe and Central Asia. Since its inception in 1999, it has been successfully held for 25 sessions.

I. Importance and Classification of Slurry Seal Coating Thickness Slurry seal is a thin-layer overlay technology composed of emulsified asphalt, aggregate, water, and additives. It is mainly used to repair minor pavement defects, improve skid resistance, and seal cracks. Its thickness directly affects durability and functionality; too thin a layer can lead to uneven coverage, while too thick a layer may cause cracking or waste costs. Based on material ratios and functional differences, slurry seals are mainly divided into two categories: Ordinary Slurry Seal: Suitable for preventative maintenance of ordinary highways, with a thickness typically of 3-6 mm.

1. Compared to ordinary slurry seal, microsurfacing uses wear-resistant aggregates, resulting in better wear resistance and skid resistance. 2. Microsurfacing has better rut repair capabilities. 3. They can prevent surface water infiltration, thus better protecting the pavement structure.

Bitumen Bagged  Melting Equipment Wholesale Manufacturer: A Comprehensive Analysis of Selection, Technology, and Application In industrial fields such as road construction and waterproofing material production,  bitumen is a core raw material, and its storage and processing efficiency directly affects project progress and cost. Traditional bitumen storage often relies on iron tanks or open-air stacking, which suffers from slow heating, high energy consumption, and significant pollution. The emergence of bitumen bagged melting equipment, through containerized transportation and intelligent heating technology, provides the industry with a more efficient and environmentally friendly solution. This article will analyze the core value of this equipment from three aspects: equipment principle, technical characteristics, and application scenarios.

Asphalt mixing plants are a crucial supporting unit behind road construction. Their production process directly affects the quality and durability of road projects. The core of their operation is transforming raw materials into asphalt mixtures that meet stringent standards.

With the arrival of the peak season for international trade procurement, our company has recently welcomed clients from many countries and regions for on-site visits and inspections. As the company continues to develop, Sinoroader has been expanding its market scale and attracting a large number of domestic and international clients to visit and inspect. Of course, high-quality products and services, advanced equipment and technology, and a promising industry outlook are important reasons for attracting clients to visit.

On March 28, 2026, a Lao customer visited our factory. Impressed by our high-quality products and services, advanced equipment and technology, and excellent brand reputation, the customer quickly decided to order a complete 10-ton kerosene-diluted emulsified asphalt equipment from us after the visit. The customer paid the prepayment on April 3.

Environmental Demand Driven by Increased Global Focus on Environmental Protection With growing global attention to environmental protection and increasingly stringent environmental regulations, the road construction industry faces immense pressure to conserve energy and reduce emissions. Traditional hot mix asphalt mixtures require heating the asphalt to high temperatures during production and construction. This not only consumes significant amounts of energy but also generates large quantities of harmful gases such as carbon dioxide, sulfur dioxide, nitrogen oxides, and asphalt fumes, posing serious threats to the environment and human health. Related research data indicates that during the production of traditional hot mix asphalt mixtures, approximately 15-20 kg of carbon dioxide and a certain amount of volatile organic compounds (VOCs) are emitted for every ton of asphalt mixture produced. These pollutants exacerbate air pollution, contributing to smog and other environmental problems.

Cold Patch Material Construction Method: 1. Cleaning the Pit: For general repairs, clean the pit and surrounding area of ​​the pit to be repaired, removing all gravel and debris. The pit should be free of mud, ice, and other impurities. When repairing excavations for highways and municipal roads, the repaired holes and trenches should have neat cut edges, and debris should be removed up to the solidified surface.
