Abstract: In order to explore the correlation between artificial accelerated aging and natural aging for HDPE net sand barriers, and establish the mathematical relationship between accelerated aging and natural aging life, this study obtained a pattern of aging test and life evaluation for HDPE net sand barriers in laboratory by analyzing the relationship of ultraviolet light and temperature between laboratory and desert environment. Also, a comparative study on the aging laws of the ordinary and anti-aging treatment net sand barriers in laboratory and desert environment was carried out. The results indicated that the laboratory life prediction model was in good agreement with the field laying data, this provides an effective method to test and evaluate the aging rule and service life of HDPE net sand barriers in specific areas.

Key words: HDPE sand barriers, ultraviolet light, temperature, life test and evaluation, tensile strength
