Research on the influence of subgrade compaction degree on road service life
路基压实度对道路使用寿命的影响研究

摘要

路基压实度是影响道路使用寿命的关键因素之一，其对道路结构的稳定性、耐久性及抗压能力具有重要作用。本文研究了不同压实度条件下路基对道路使用寿命的影响，探讨了路基压实度与道路质量之间的关系。适当的路基压实度能有效延长道路使用寿命，减少路面损坏与维修频率。而不合格的压实度则可能导致路面沉降、开裂等问题，严重影响道路的稳定性和使用效果。本文通过对不同压实度下道路性能的分析，提出了优化压实度控制的建议，以期为提高道路质量和延长使用寿命提供理论依据。

Abstract

Subgrade compaction degree is one of the key factors affecting road service life, playing a significant role in the stability, durability, and compressive capacity of road structures. This paper studies the impact of subgrade compaction degree on road service life under different compaction conditions and explores the relationship between subgrade compaction degree and road quality. Appropriate subgrade compaction can effectively extend road service life and reduce pavement damage and maintenance frequency. In contrast, unqualified compaction may lead to issues such as pavement settlement and cracking, seriously affecting road stability and service performance. Through the analysis of road performance under different compaction degrees, this paper proposes suggestions for optimizing compaction control, aiming to provide a theoretical basis for improving road quality and extending service life.
