When we drive on the road, few people notice the seemingly ordinary structures on the side of the road-the shoulder. But in fact, it plays a vital role in ensuring traffic safety. The shoulder can not only guide the vehicle into the lane area correctly, but also effectively prevent soil erosion and protect the road surface from external erosion damage. It can be said that without a solid and reliable shoulder support, the entire road traffic system will lose its stable foundation.

So, among the many optional materials, how should you decide which is the most appropriate choice? At present, there are mainly three types on the market for reference: first, traditional concrete products are widely used because of their low cost and mature production technology; Secondly, although natural stone has beautiful appearance and strong durability, its price is relatively high and its construction is difficult. Finally, various composite environmental protection building materials emerging in recent years combine the advantages of both to ensure strength and take into account economy.

in addition, special demand problems brought about by differences in specific application scenarios should also be taken into account. for example, urban trunk roads are frequently braked and started due to intensive traffic flow, so it is suggested to give priority to traditional prefabricated block components with excellent compressive performance and long service life to construct slope protection system, so as to minimize maintenance frequency and reduce financial expenditure burden. for some remote mountainous areas or rural tourism roads, local resources can be used to reduce costs. At the same time, the investment has also promoted the development of local economy and formed a virtuous circle mode.

facing the dazzling array of market supply information, how to quickly and accurately screen out the ideal options that really suit one's own situation has become a challenging topic that every purchasing decision maker must face. therefore, we have summarized several core evaluation criteria for everyone to learn from, including but not limited to the following dimensions: first, define the budget scope and delimit the basic threshold line, then comprehensively examine the supplier's qualification and credibility to ensure reliable product quality, and then carefully study the contract terms to avoid potential risks and hidden dangers. Finally, the field survey model project site to listen to the advice and guidance of professional and technical personnel in order to make a scientific and reasonable judgment conclusion.

in order to better demonstrate the practical application effect of the above theoretical knowledge, we specially selected a typical case to analyze and introduce a new highway section project in a city. through preliminary full investigation and demonstration, the integral continuous guardrail structure assembled by standard standardized module units made of high-performance fiber reinforced cement-based mixture has not only successfully achieved the expected planning objectives, but also won high evaluation and recognition from peers in the industry, which is worthy of imitation and promotion of other similar projects. Use.
