Dear Current Administrators of TBA, Stop erasing posts and topics. All of you. As a regular of TBA who loved it dearly, you have no idea how much it kills me that so many topics were left to the trash without member consent. And it wasn't just drama posts -some of you deleted any post that you didn't like, from roleplays, from anything...you deleted the entirety of A Very Potter Roleplay, as an example. As the creator of that roleplay, I realize it was somewhat of a failure, but the fact that it was erased without my consent is upsetting, and there were a few members who enjoyed it. I realize that there were some things posted on TBA that many of us are not proud of. Drama and the like. But even with that drama, TBA was so, so, important to me, and others. Yet, certain moderators have ignored this and have erased topic upon topic -that showed in the Administrator history. Even if you say it was only a single topic or a single post, the forum has been trimmed down. You say this is only "cleaning up the forum," but it's erasing our history, and I won't stand for it. To those of you who've returned to this forum only to remove things periodically, please stop. It simply isn't fair to those of us who are nostalgic and like looking back, and I know I don't speak of myself alone. With all due respect, LL.

<P> segregation of asphalt pavement in the road refers to a region of the main properties of asphalt is uneven, including asphalt content, gradation composition, additive content and porosity of the road, so as to accelerate the asphalt pavement damage. Some highway asphalt pavement early damage, such as damage caused by the water network cracking, deformation and potholes, severe local Rut, local weeping, multi-lateral cracks, texture depth newly paved asphalt road unevenness, etc., with bitumen segregation Related mixture. </P>
<P> From a macro perspective, hot mix asphalt segregation are basically three types: </p>
<P> (1) Gradation Segregation hot mix asphalt improper operation in the production, transportation, paving process resulting mixture aggregate thickness uneven distribution of produce segregation. Porosity of coarse aggregate more concentrated large asphalt pavement, asphalt content is low, resulting in asphalt pavement water damage and a decrease in durability, resulting in fatigue cracks, potholes and flaking and other diseases; fine aggregate more concentrated area porosity small asphalt pavement, asphalt content of large, prone to rutting, weeping and other diseases. </P>
<P> (2) temperature of the hot mix asphalt segregation during transport, paving, since the temperature of the mixture at different positions fall inconsistent, leading to differences in temperature mixture, a temperature segregation. Mixture haul vehicle surface, material transport vehicles on both sides of the trunk and paver wings mix is ​​easy to produce temperature segregation. </P>
<P> (3) aggregate - asphalt isolation large amount of oil mixes prone to such segregation, similar to asphalt mixture analysis drain, SMA mix is ​​easy to produce such segregation. </P>
