UHPC bridge deck transverse unequal-thickness asphalt paving construction process
The invention discloses a UHPC bridge deck transverse unequal-thickness asphalt paving construction process. The paving construction process comprises the following steps of: 1, construction preparation; 2, measuring and setting out; 3, mixing of asphalt mixture; 4, transportation of the asphalt mixture; 5, paving of the asphalt mixture; 6, grinding of the mixture; 7, joint treatment; and 8, detection and inspection. Specifically, the construction preparation content in the step 1 comprises the steps that: (1) before the lower surface layer of a main bridge is paved, splicing inspection of a paver, the camber and the abrasion condition inspection of a bottom plate are conducted; (2) a blind ditch is reserved by erecting a formwork on the most edge of the main bridge in advance, a 3cm*6cm square pipe is adopted as the formwork, and 4cm*4cm wood blocks are placed on the outer side of the square pipe every 2m, tightly attached to an outer side guardrail and used for fixing the reserved blind ditch formwork; according to the UHPC bridge deck transverse unequal-thickness asphalt paving construction process, the constructed bridge deck is high in quality and long in service life, the quality of each link of the paved bridge deck can be guaranteed, and adjustment can be made in time.
本发明公开了一种UHPC桥面横桥向不等厚沥青摊铺施工工艺，摊铺施工工艺包括以下几个步骤：步骤一：施工准备；步骤二：测量放样；步骤三：沥青混合料的拌和；步骤四：沥青混合料的运输；步骤五：沥青混合料的摊铺；步骤六：混合料的碾压；步骤七：接缝处理；步骤八：检测及报验，所述步骤一中施工准备内容包括：（1）主桥下面层摊铺前，先进行摊铺机拼接检查、拱度及底板磨耗情况；（2）提前在主桥最边部支模预留盲沟，模板采用3cm*6cm方管，方管外侧每隔2m放入一块4cm*4cm木块，紧贴外侧护栏，用于固定预留盲沟模板。该UHPC桥面横桥向不等厚沥青摊铺施工工艺，施工的桥面质量较高，使用寿命较长，且能够保证摊铺后桥面每一环节的质量，并及时作出调整。
