The present invention relates to a tire tread rubber composition for a construction vehicle with improved wear resistance, and more particularly, to a tire tread rubber composition for a construction vehicle, which can reduce viscosity by including polytransoctenamer and has improved processability and wear resistance. The tire tread rubber composition of the present invention comprises 50 to 60 parts by weight of a carbon black having an iodine adsorption value of 116 to 121 g/kg and a dibutyl phthalate adsorption value of 109 to 114 cc/100 g with respect to 100 parts by weight of a raw rubber including 50 to 70 parts by weight of a natural rubber and 20 to 35 parts by weight of a butadiene rubber having 94 to 98 wt% of cis content. The raw rubber further includes 5 to 20 parts by weight of polytransoctenamer.
본 발명은 내마모성이 향상된 건설차량용 타이어 트레드 고무조성물에 관한 것으로, 더욱 상세하게는 폴리트랜스옥테나머를 포함되도록 하여 점도를 낮출 수 있을 뿐만 아니라 가공성 및 내마모성이 향상된 건설차량용 타이어 트레드 고무조성물에 관한 것이다. 이러한 본 발명은, 타이어 트레드 고무조성물에 있어서, 천연고무 50~70중량부와, 시스 함량이 94~98wt%인 부타디엔고무 20~35중량부를 포함하는 원료고무 100중량부에 대하여, 요오드 흡착가가 116~121g/kg이고, 디부틸프탈레이트 흡착가가 109~114cc/100g인 카본블랙 50~60중량부를 포함하여 형성되는 것으로, 원료고무는, 폴리트랜스옥테나머(poly transoctenamer) 5~20중량부를 더 포함하는 것을 특징으로 하는 내마모성이 향상된 건설차량용 타이어 트레드 고무조성물을 기술적 요지로 한다.
