Acrylic stadium requirements for cement and asphalt base
   平整度：
Flatness:
   基础应具有一定的强度和稳定性。基础不能产生裂缝和由于冰冻引起的不均匀冻胀。平整度合格率在95%以上，3米直尺误差3mm。
Foundation should have a certain degree of strength and stability. The foundation can not crack and the uneven frost freeze induced. Flatness qualification rate in more than 95%, 3 meter ruler error 3mm.
   坡度：
Slope:
   横向<0.1‰，纵向<1‰，跳高区<4‰，表面应平坦光滑保证排水。
Lateral <0.1 ‰ <1 ‰, vertical jump, <4 ‰, the surface should be flat and smooth to ensure drainage.
   强度和稳定性：
Strength and stability:
   沥青基础最好采用不含腊，或含腊很少的沥青材料，其沥青混合料必须充分压实。表面均匀坚实，平整无裂纹，无烂边堆挤，无麻面，接缝平顺光滑。沥青混凝土面层碎石粒径为2—5mm，含油量5.8—6.4%，接合层碎石粒径为6—9mm，含油量4.6—5.8%。压实密实度不得小于95%，在中型碾压机压过后，无显著轮迹，无发软起皮，无浮土松散，波浪等现象。
