JTGF。-(公路水泥混凝土路面施工技術(shù)規(guī)范》首次明確了路面混凝土可采用機(jī)制砂，并規(guī)定高速公路混凝土路面用機(jī)制砂單粒級顆粒大壓碎值應(yīng)小于％～%(質(zhì)量分?jǐn)?shù))，石粉含量應(yīng)小于%～%(質(zhì)量分?jǐn)?shù))，并且砂中硅質(zhì)含量應(yīng)不低于%(質(zhì)量分?jǐn)?shù))．有關(guān)機(jī)制砂混凝土的路用性能，特別是針對機(jī)制砂混凝土耐磨性影響的研究未見報(bào)道，這制約了機(jī)制砂在混凝土路面工程中的應(yīng)用。?ú?ù?ü?a￡?×??üú?òò??±?úìá?·￠?μíì??ú???·±￡￡????oì?ê??òú??òa?-??à′?′??ò?￡??ú×ê?′′óá??aéμ?yì?D￡?±?è?úéúá?ò?D?·??ú???￡???oí·êˉ?óòμìì?·???μ?ò????￡???oí·êˉμ?úéú?á??aé?oì?￡??óD?ú?′?o§μ??′í·?￠?oì?éúú?Dμ?ê???í·?￠°??o??oí?ò???ò???D???μ??ooí?òêˉò??°oí?oí·êˉò??e??·?μ??o?μ??íaμ?°×í·μèμ??ìo????￡。?Y?à?êy?Y??ê?￡????°à?????′?á?ò??yòú??￡????ò???êè?ò?òú?à??μ??ù?èμY???￡è???????oí·êˉ?ú???ó?￡???ó?′ó??íáμ??￡?oí·êˉ?Dμ?áò?ˉ??òY??ò?t??á??è?′ó???￠??ì?oí??ì??￡í·êˉé???á×?è?·￠éú?e??￡??ò?úóê??±à?ú￡?óùè?oóá÷?ìé??o|?￡°é???oì?ú???￡μ?à?′ó,?oí·êˉúá???????ó,?ìéμ??·??êìaè?ò?í??￡???àíè???è?ò??è?T,?oí·êˉμ?′|àíoíà?ó?￡?ò?é?aoü?à?oì??óòμ·￠???ì?D??áùμ?í???êìa??ò??￡。????óúμ±???-???ü?′D?ê??￡?ú￡??òú?t??ò??±??μ÷oí??êó?ú???ü?′￡?′ù??×ê?′μ?×?o?à?ó?￡?·￠?μíì??-??￡??¨éè?ú??Díé??á￡?±￡?¤éúì??·??￡?￡?Y?Y°??úDμ×°±?óD?T???????μ±?°?oí·êˉμ???ê??ùà?ó??ê?a?ò??μáDμ?′|àí?D????μ???′óí???￡??D·￠′ò?ìμ?′óDíò|ê????é?ú￡?·′?÷ê????é?úò??°?×????é?ú￡??éò????oí·êˉ??DD?ó¤???é?ú￡?à?′ó??à?ó?μ?·??§￡????éó?óú??×??￠·￠μ?￡??-??·??ú?￠?￥·??ú??·?oó?éó?óú???à?￠?ì?yíáéúúμèμè￡??oí·êˉ???é?ú×÷ó???′ó￡?′|àí?oí·êˉà?ó??ê??′?%ò?é?￡????yμ
