【摘要】：目前,我國(guó)大多數(shù)的城市道路、公共廣場(chǎng)等的鋪面設(shè)計(jì)均采用與“自然協(xié)調(diào)發(fā)展、生態(tài)良性循環(huán)”理念相違背的不透水型密級(jí)配混凝土和石板材鋪裝結(jié)構(gòu),這種路面鋪裝的大面積使用會(huì)對(duì)城市生態(tài)環(huán)境造成負(fù)面影響。生態(tài)型透水路面結(jié)構(gòu)特點(diǎn)不同于普通路面,能夠調(diào)節(jié)大氣濕度,具有良好的環(huán)保生態(tài)效益。因此,本文對(duì)生態(tài)透水瀝青路面材料組成進(jìn)行研究并對(duì)其結(jié)構(gòu)組合進(jìn)行設(shè)計(jì),主要研究?jī)?nèi)容包含以下幾部分:(1)對(duì)我國(guó)透水路面應(yīng)用狀況進(jìn)行全面調(diào)查,查明透水路面實(shí)體工程的配比組成以及相關(guān)性能指標(biāo),參考現(xiàn)有規(guī)范對(duì)原材料的技術(shù)要求,提出新的更加科學(xué)合理的原材料技術(shù)指標(biāo)要求,為透水路面材料組成設(shè)計(jì)提供參考依據(jù)。(2)提出基于降雨強(qiáng)度的透水路面設(shè)計(jì)分級(jí)標(biāo)準(zhǔn),研究不同降雨條件時(shí)透水路面所需空隙率及路面設(shè)計(jì)要點(diǎn),并進(jìn)行透水瀝青混合料配合比設(shè)計(jì)。(3)對(duì)透水路面相關(guān)規(guī)范進(jìn)行系統(tǒng)調(diào)查,提出透水路面路用性能評(píng)價(jià)指標(biāo)建議值,系統(tǒng)研究不同空隙率的級(jí)配對(duì)透水瀝青混合料路用性能的影響規(guī)律,為透水路面的實(shí)際工程應(yīng)用奠定基礎(chǔ)。(4)針對(duì)目前常用的透水瀝青路面結(jié)構(gòu)型式,建立力學(xué)分析模型對(duì)透水瀝青路面結(jié)構(gòu)組合方案進(jìn)行分析評(píng)價(jià),提出基于荷載應(yīng)力綜合響應(yīng)的透水瀝青路面結(jié)構(gòu)優(yōu)化組合,為透水瀝青路面結(jié)構(gòu)組合設(shè)計(jì)奠定基礎(chǔ)。(5)通過生態(tài)透水瀝青路面實(shí)體工程的實(shí)施,建立透水瀝青路面彎沉、抗滑性能、透水性能及平整度為主的施工質(zhì)量檢測(cè)體系,為透水路面在天津乃至全國(guó)范圍的推廣應(yīng)用提供技術(shù)借鑒。
[Abstract]:At present, the pavement design of most urban roads and public squares in our country adopts impermeable dense graded concrete and stone slab pavement structure, which is contrary to the concept of "harmonious development of nature and benign cycle of ecology".The extensive use of this pavement will have a negative impact on the urban ecological environment.The structure characteristics of ecological permeable pavement are different from those of common pavement, which can adjust air humidity and have good environmental protection ecological benefit.Therefore, this paper studies the composition of ecological permeable asphalt pavement materials and designs its structure combination. The main research contents include the following parts: 1) the application of permeable asphalt pavement in China is investigated comprehensively.To find out the proportion composition and related performance indexes of the solid engineering of permeable pavement, and refer to the technical requirements of raw materials of existing specifications, put forward new and more scientific and reasonable technical requirements of raw materials,This paper provides a reference basis for the material composition design of permeable pavement. (2) A classification standard for the design of permeable pavement based on rainfall intensity is put forward, and the voids required by the permeable pavement under different rainfall conditions and the key points of pavement design are studied.A systematic investigation on the relevant specifications of permeable pavement is carried out, and the suggested value of evaluation index of permeable pavement performance is put forward, and the mixture ratio design of permeable asphalt mixture is carried out.The influence of gradation of different voids on pavement performance of permeable asphalt mixture is systematically studied, which lays a foundation for practical engineering application of permeable asphalt pavement.A mechanical analysis model is established to analyze and evaluate the structure combination scheme of permeable asphalt pavement, and the optimal combination of permeable asphalt pavement structure based on the comprehensive response of load and stress is proposed.Laying a foundation for the structural combination design of permeable asphalt pavement. (5) through the implementation of the entity engineering of ecological permeable asphalt pavement, a construction quality inspection system with deflection, skid resistance, water permeability and smoothness of permeable asphalt pavement is established.It provides technical reference for the popularization and application of permeable pavement in Tianjin and even all over the country.
