一、仪器用途及原理
SYD-0613沥青脆点试验器 (弗拉斯法)是根据中华人民共和国行业标准JTJ052《公路工程沥青及沥青混合料试验规程》中的T0613《沥青脆点试验(弗拉斯法)》规定的要求设计制造的,适用于按JTJ052—T0613标准所规定的要求,测定沥青材料的弗拉斯脆点。
沥青材料随着温度的降低,由“粘—塑性”状态逐渐转变为“弹—脆性”状态。因而表现为塑性减小,脆性增加。本仪器即是在低温条件下测定沥青的脆点。
本试验仪器是在一特制的金属片上涂一层沥青薄膜,在装有冷却装置的保温筒内,通过手柄使金属片弯曲,随着温度的降低沥青薄膜温度亦逐渐降低,当降至某一温度时,沥青薄膜在规定弯曲条件下产生断裂时的温度(用酒精温度计显示)即为沥青的脆点。

SYD-0613 asphalt brittle point tester ( Fulasifa ) is based on the standard of people's Republic of China JTJ052 " highway engineering asphalt and asphalt mixture test procedures " in T0613 " asphalt brittle point test ( Fulasifa " ) in accordance with the requirements of design and manufacture, applied to JTJ052 - T0613 standard requirements, the frasnian of Bituminous Materials brittle point.

Asphalt material as the temperature is lowered, the " sticky plastic " gradually transformed into " elastic brittle .". And thus the performance of plastic to reduce, increase in brittleness. The instrument is in the condition of low temperature of asphalt brittle point.

The test apparatus is in a special metal sheet is coated with a layer of asphalt film, in a cooling device of heat-insulating barrel, through the handle to make the sheet metal bending, decreases with increasing temperature asphalt thin film temperature was also decreased, while to a certain temperature, asphalt thin film under bending conditions when the temperature crack ( alcohol thermometer display ) is the asphalt brittle point.
